Demand Turn Up

The Demand Turn Up (DTU) service encourages large energy users and generators to either increase demand or reduce generation at times of high renewable output and low national demand. This typically occurs overnight and during weekend afternoons in the summer. Find out about routes to market as a provider.

There are two forms of payment that we will make as part of the demand turn up (DTU) service:

availability payment – to Fixed DTU providers for being available to provide the service; and
utilisation payment – to Fixed and Optional DTU providers for delivering the service when instructed.

Providers have the flexibility to submit their own prices for the service. These prices will inform the economic assessment to determine which parties are accepted.

Fixed service

For the fixed service, providers state at the tender stage the prices they wish to receive for availability and utilisation. These will then be fixed for the duration of the service term.

Optional service

For the flexible service, providers can change their prices as frequently as twice a week, on a Friday and Tuesday, to reflect market conditions.
